Tabua is a new transpacific subsea cable connecting the United States and Australia to Fiji.

Named after a sacred Fijian whale’s tooth, the Tabua cable system is part of Google's South Pacific Connect initiative which includes Tabua and Honomoana, which connects the United States and Australia to French Polynesia. 

In addition to Honomoana and Tabua, the South Pacific Connect initiative will construct physically diverse cable landing stations in Fiji and French Polynesia and connect them with an interlink cable. 

The South Pacific Connect initiative will create a ring between Australia, Fiji and French Polynesia. This ring will include pre-positioned branching units that will allow other countries and territories of Oceania to take advantage of the reliability and resilience resulting from the initiative. 

In April 2024, Google announced to extend the Tabua subsea cable to Hawaii and build the Taihei subsea cable connecting Hawaii with Japan.

The Tabua cabele system is privately owned and controlled by Starfish Infrastructure Inc. (Starfish), an indirect wholly owned subsidiary of Google LLC. Both Google and Starfish are incorporated in Delaware, the United States.

The Tabua cable system consists of 16 fiber pairs on its trunk and branching segments, and each fiber pair is designed with a minimum capacity of approximately 17 Tbps per fiber pair using current technology, for a total system capacity of 272 Tbps, with:

• Transpacific Trunk: between Los Angeles (Equinix LA4), California, and New South Wales, Australia, 13,323 kilometers.
• Oahu Segment: connecting the Hawaiian Island of Oahu to a branching unit on the Trunk, 318 kilometers.
• Suva Segment: connecting Suva, Fiji, to a branching unit on the Trunk,  114 kilometers,  114 kilometers.
• Natadola Segment: connecting Natadola, Fiji, to a branching unit on the Trunk, 305 kilometers.
• Queensland Segment: connecting Queensland, Australia to a branching unit on the Trunk, 691 kilometers. The segment lands at NEXTDC Sunshine Coast Cable Landing Station (NEXTDC SC1) in Maroochydore, Sunshine Coast, where hosts JGA South and 

The Tabua cable system includes an unused branching unit near the Oahu segment, without current plans to utilize this branching unit. 

The Tabua cable system is the first continental U.S. system that has two landing points in Australia and two landing
points in Fiji, on both the east and west sides of the main island of Viti Lev, Fiji. Such dual landings provide path diversity, redundancy in island connectivity in case of a single branch failure, and greater resiliency by supplying the cable with single end power source capability. 

Starfish intends to install and test the Tabua cable system in US waters starting in the third quarter of 2025 and commence commercial operation of the US landing points of the Tabua cable system in the first quarter of 2026.
